In laws getting cooling

I never understood why my in-laws would not use their air conditioner. They would walk around dripping with sweat, feeling miserable and complaining about the heat all summer long, however they would never take the initiative to close up the windows, turn the temperature control down and crank up the air conditioner. I was constantly sneaking around and turning the temperature down on the thermostat in the hallway next to the bedrooms, however they’d inevitably catch me and tell me to just open a window. Then they’d turn the temperature control back off again. I even told them that I’d pay the utility bills when they came in the mail, if only they would let me turn the temperature down on the HVAC system and start the air conditioner. It was usually 76 or 77 degrees in their home and it felt so stuffy to me that I could barely even stand it! I get so sweaty, crabby and mean when I’m hot that I can’t figure out why my husband and I stayed married during the year that we had to live with my in-laws. He must’ve been used to it since he lived with them while he was growing up, however my parents were great proponents of air conditioning during the Summertime! My dad would crank it all the way down to 63 or 64 or some days and we would just sit inside relaxing in the cool air as it blew through the air vents. It was so nice to be cold even though outside the temperature was in the high 90s.
